LP2980-ADJ

Overview

The LP2980-ADJ is an adjustable-output, wide-input, low-dropout voltage regulator supporting an input voltage range up to 16 V and up to 50 mA of load current. The LP2980-ADJ supports an output range of 1.2 V to 15.0 V (new chip) and 1.23 V to 15.0 V (legacy chip).

  • VIN range: - Legacy chip: 2.2 V to 16 V - New chip: 2.5 V to 16V
  • VOUT range: - Legacy chip: 1.23 V to 15.0 V - New chip: 1.2 V to 15.0 V
  • VOUT(typ) accuracy: - Legacy chip: ±1% - New chip: ±0.5%
  • Output accuracy over load and temperature: - Legacy chip: ±3.5% - New chip: ±1%
  • Output current: Up to 50 mA
  • Quiescent current, low IQ (new chip): - 55 μA at ILOAD = 0 mA - 350 μA at ILOAD = 50 mA
  • Shutdown current over temperature: - Legacy chip: < 1 μA - New chip: ≤ 0.8 μA
  • Output current limiting and thermal protection
  • Stable with 2.2-µF ceramic capacitors (new chip)
  • High PSRR (new chip): - 70 dB at 1 kHz, 42 dB at 1 MHz
